v ANTON TEHNIK, OF RONNOW, BOHEMIA, AUSTRIA-HUNGARY.

WEDGE-BUCKLE.

SPECIFICATION forming part of Letters Patent No. 426,401, dated April 22, 1890..

Application filed December 2,1889. Serial No. 332,383. (No model.)

To all whom it may concern:

Be it known that I, ANTON TEHNIK, of Ronnow, in the Kingdom of Bohemia, Austria-Hungary, have invented new and useful ledge-Buckles, of which the following is a specification, reference being had therein to the accompanying drawings.

This invention relates to the manufacture of an improved buckle or fastening in whichthe usual prong is dispensed with, and which buckle will allow of the extremities of, say, two driving-belts being rapidly, safely, and thoroughly fastened together without being liable to damage or injury, and which buckle is equally applicable as a fastener for other analogous purposes.

This improved buckle or fastener is fully illustrated in the accompanying drawings, in which- Figure I is a top view of a double wedgebuckle. Fig. II is a transverse sectional view of Fig. I on line C D. Fig. III is a longitudinal section of Fig. I on line A B. Fig. IV is a tip view of a single wedgebuckle. Fig. V is a transverse sectional view of Fig. IV on line C D. Fig. VI is a longitudinal sect-ion of Fig. IV on line A B.

The same letters of reference are used to denote identical parts in all the views.

The principle of this wedge-buckle is based chiefly upon the following fact, viz: The two belts connected together by this device are not only incapable of being loosened or released by pulling, however hard, at the two opposite belts, but that, on the contrary, the connection becomes tighter and more secure in proportion as the strain exerted thereon is increased, as the wedge-shaped locking-piece, hereinafter described, is caused by such pulling action to be still more firmly wedged or clamped within the tapered grooves provided oneach side of the buckle.

Fig. I shows a double ,or duplex buckle on this principle,in one end of which one of the extremities of the belt is shown inserted in the sheath a. The side cheeks b of this sheath, which are bent over at the top, have a tapered or wedge-like form, corresponding to that of the similarly-tapered sides 0 of the locking device d, the latter having its transverse edge e, or that adjoining the lower or narrowest end of the bent-over edge 17, bent upward, and which bent part 6 thus serves on the one hand as a locking-handle and on the other as a guide, as each of its extremities is provided with a groove f for sliding upon the bent-over edges of the side checks 5, the projections 9 upon the edge of the checks 1) serving to prevent the locking-piece d sliding off in front. The lower side of the said locking-piece d, where the same comes in contact with the belt, is grooved, serrated, or otherwise roughened, so as to have a better hold on the leather. It will be easily seen that when the end of the belt is placed in the sheath a and the locking-piece cl is pushed over the same the latter must look itselfthat is to say, be pressed all the harder upon the surface of the belt in proportion as the pull thereon is greater-while the bent-up wedge-like sides 0 of the locking-piece d are drawn (in consequence of the pull upon the belt) deeper within the tapered grooves, thus rendering the looking or wedging action upon the belts accordingly tighter.

In Figs. IV, V, and VI the two belts. h and 'i are laid over one another, the locking piece or wedge j being pushed over the same and provided in this case with a wider cover than that shown in Fig. I. When the two belts are placed over one another, care must be taken that the soft side of the upper belt should be upon the upper side of the lower belt.

In buckles such as heretofore used and provided with a prong which enters one of the holes formed in the belt it was highly inconvenient and awkward to bring the desired hole in sufficiently close contact to the prong, and the solidity and strength of the belt were interfered with and diminished by piercing the same, the buckle also without prong and with an articulated folding locking device ceased in most cases to be effective after a short use,while the locking-lever became bent and allowed the belt to slide off. All these defects are fully met and remedied by the wedge -buckle above described, which possesses the greatest advantages, particularly in the case of traces used for yoking horses and other draft-animals on account of its being so easily handled and of its absolute safety. It is equally applicable to other analogous fastening purposes.

WVhat I claim, and desire to secure by Letters Patent of the United States, is-

1. In a buckle, the combination, with the sheath provided with the inclined cheeks extending inwardly over the bottom of the same, of the wedge-piece consisting of a flat portion 10 having upturned edges at opposite sides inclined to engage the under face of said cheeks, and having also an upturned transverse flan ge notched at each end to engage the said cheeks, substantially as described.

2. In a buckle the combination, with the sheath provided with the inclined cheeks extending inwardly over the bottom of the sheath, of the Wedge-piece having upturned edges engaging said cheeks and an upwardlyextending flange at one end recessed to engage ANTON TEHNIK. Witnesses:
